I understand that the Blown-Diffuser has been banned, now does that mean that you cannot direct airflow through the car and out different parts of the under-tray(like red bull have a tunnel under their sidepods into a hole in the under-try), so I was just wondering if you could direct airflow through the car from different points and then direct it through a hole in the under-tray like what red bull have done since it would not be interfering in the diffuser areas would that still be legal ?
